BABY-WALKER.

SPECIFICATION forming part of Letters Patent No. 592,569, dated October 26, 1897.

Application filed September 23. 1896. Serial No. 606,711. (No model.)

To all whom t may concern:

Be it known that I, RICHARD LEHMANN, a citizen of the United States, and a resident of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Baby-Chairs, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof, in which similar letters of'refro erence indicate corresponding parts.

This invention relates to baby chairs or devices of that type in which the child is retained and held in upright position while walking.

I 5 The object of my invention is to provide'a simple and improved baby chair or walker of this class in which the movement of the device will be governed with relation to a iiXed point, which will be locked against rearward 2o movement and which will furthermore possess advantages in point of safety, convenience, ease of operation, and general efficicncy.

In the drawings, Figure l is a perspective view showing the device complete. Fig. 2 is a rear end elevation showing the pivot mechanism in section, and Fig. 3 is a vertical longitudinal sectional view of the chair or crib.

3o Referring to the drawings, A designates the chair, which is adapted to inclose the child and retain the same safely in position. This chair may be in the main of any suitable construction, but preferably embodies a base- 3 5 frame a, from which rises arail a', surrounding the device, as shown, and preferably embodying the open-spindle construction a2 in its connection with the base-frame.

The base-frame is mounted upon legs B,

4o preferably arranged, as shown, with a single leg centrally at the front and a pair of legs at the rear end of the device. These legs carry rollers or casters b.

At the rear end of the baseframe a is provided a seat C, which may be of commode form or construction, as shown at c, and a drawer D may be provided below said seat, said drawer being arranged to work upon cleats d d, longitudinally arranged under the 5o seat O, the inward movement of the drawer being limited by a cross-strip d. The drawer may be provided at its rear end with a springcatch, which preferably consists of a flat spring-plate E, having an angular projecting top end e, adapted to engage a' recess e in 55 the under side of the seat portion of the baseframe.

I provide at the front end of the rail a a table F, which has a concave or segmentallycurved rear end f andis adapted to slide 6o longitudinally, so that the child is held in position between this rear curved edge fand the similarly-curved front edge c of the seat C.

The longitudinal movement or adjustment of the table F is preferably governed by a coiled spring G, mounted in a longitudinal bracket I-I, projecting at the bottom of the table and adapted to embrace the front end portion of the rail a. This bracket thus serves to retain the table in connection with 7o the rail, and to obviate lateral displacement of the table the front edge of the rail a has a recess, as indicated in dotted lines at f', to receive the base portion of the table.

The chair or baby-walker is adapted to be connected to a pivot device forming a fixed point around which the chair will have a circular line of travel, and for this purpose I provide a turn-table or plate I, upon which is pvotally mounted a horizontal hub J, carry- 8o ing at one side radial arms K. These arms are preferably three in number and extend, respectively, to the front leg B and the inside rear leg approximately in horizontal plane, while the central or intermediate arm extends upward in inclined position to the rail a'. .A This relative arrangement of the radial connecting-arms eifectively braces the chair device in upright position during its travel. 9c

' The turn-table may be secured in position upon the floor by means of screws Z, and it may be secured outdoors in position upon the ground by means of a stake L passing through a central eye or opening in the turntable and driven a suitable distance into the ground.

Upon the top surface of the turn-table or plate I is provided an annular ratchet e', adapted to be engaged by pawl j, pivotally roo mounted upon the outer end of a lateral arm j', projecting from the rotary hub J. B y reason of this construction and arrangement the chair or walker is adapted to freely travel in a forward direction, but is locked against rearward movement by operation of the ratchet mechanism.

The operation and advantages of my invention will be readily understood.

The chair or walker is adapted to safely and properly retain a child in position and permit a free walking movement in a circular plane around the fixed point' formed by the turntable. Danger of accident and the risk of a free and unrestricted ,line of travel for the child when retained in the chair is thus ob-` viated.

The chair is also firmly braced in upright position by its connection with the turn-table, and by reason of its being locked against any rearward movement whatever theI effort of the child is always exerted in a forward direction.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a device of the class described, the coin- .bination, with a turn-table or pivot-plate, of

RICHARD LEHMANN.
